Batch Control & Traceability

Each batch receives a unique lot number and is managed under controlled laboratory conditions to preserve stability and ensure full traceability. Analytical results refer only to the specific batch tested and current stock from that batch.

Independent Third-Party Testing

Representative samples are submitted to an accredited external laboratory. Validated, industry-standard methods include:

• HPLC — purity and impurity profiling.
• LC-MS — peptide identity confirmation by mass/spectral analysis.
• FTIR — spectral identity verification vs certified references where applicable.

Microbiological & Safety Screening

Additional screening performed as part of analytical completeness:

• Bioburden (USP <61>)
• Bacterial endotoxin (USP <85>, chromogenic)
• Elemental impurities screening (arsenic, cadmium, lead, mercury, nickel, cobalt, vanadium)

Controlled Handling & Packaging

Materials are handled in controlled environments, weighed on calibrated balances, and sealed in sterile containers. Only batches meeting acceptance criteria proceed to packaging and distribution.

Transparency & Verification

Full Certificates of Analysis (COAs) are published on our website. Each COA contains batch/lot details, methods used, lab references, test dates and the batch-specific results—enabling independent review.

Intended Use

Products are supplied as traceable, analytically-verified materials intended for laboratory and scientific use only.

Analysis results apply only to the samples tested. COAs support traceability and should be interpreted within a research laboratory context.
